Specification of Letters Patent. Patentd July 12, 1910.

Application filed August 26, 1909. Serial No. 514,708.

To all whomit may concern:

Be it known that I, TAYLOR W. HEINTZEL- MAN, of Sacramento, in thecounty of Sacramento and State of California, have in.- vented a certainnew and useful Improvement in Freight-Car Doors, of which improvementthe following is a specification.

My present invention relates to metal doors for freight cars, and itsobjectis to provide a door, applicable eitherto wooden or steel cars,which shall be of simple, durable, and inexpensive construction, readilyoperable, and effectually preventive of pilfering from cars/and damageto lading by access of water or dust. i

,The improvement claimed is hereinafter fully set forth.

In the accompanyingdrawings: Figure 1 is an outside "iew, in elevation,of a freight car door embodying my invention; Fig. 2, a vertical sectionthrough the same, on the line a a of Fig. 1; Fl 3, a horizontal sectionon the line I) Z) of Fig. 1; Fig. 4, a horizontal section, on anenlarged scale, on the line 0 c of Fig. 1, showing the door closed; Fig.5, a similar section, showing the door partly open; Fig. 6, a verticalsection, on the line (a a of Fig. 1; and, Fig. 7 a similar section, onthe line a? a of Fig. 1.

In the practice of my invention, I provide a door comprising two leaves,1, 1, of plate metal, as, say 9; inch steel, which are connected to thedoor posts, 2, 2, of the car, by

hinges, 3, 3, of the ordinary type, and fit closely together on theiropposite sides. The leaves are stiffened bydiagonal braces, 4, 4, ofangle iron, riveted to their inner sides,

and by angle plates, 5, 5, riveted to their inner sides at their topsand bottoms. In order to guard against burglarizing cars, which isdoneto a considerable extent when the usual sliding doors are used, as wellas to form a practically water tight and dust proof joint, a Z bar, (3,is riveted to the inside of each of the leaves, 1, 1, adjacent to thehinged side thereof, said 2 bars fitting closely against the door posts,with their outer flanges fitting in vertical grooves, 2*, therein, whenthe door is closed, as shown in Fig. 4.

The leaves of the door when closed, fit into recesses, ofdepthcorresponding to their thickness. in-the side sills, 7, of the carframe, and their lower angle plates, 5, fit closely over metal plates,8. secured to the tops of the sills, as most clearly shown in Fig. 7,

this construction making a water tight and substantial joint. The topsof the leaves fit similarly into recesses in the roof side plates, 9,and their angle plates, 5, fit against the bottoms of the roof plates,as shown in Fig. 6. To prevent Wear of the door posts, side sills, androof plates, they are preferably, as shown, protected by metal facingplates, 10, the facing plates of the side sills being substantially inthe same horizontal plane as the bottom angle plates of the door leaves.

The door is latched and held closed by a vertically sliding latch, 11,made in two sections, which are coupled to and operated by a hand lever,12, and which slide in clips, 13, secured to the door leaves, and clips,l l

and 15, on the roof side plate andside sill,-

respectively. "Lap plates, 16, 17, are riveted to the inner side of oneleaf and the outer side of the other, said plates covering and makingtight the 'joint of the leaves when closed. I a

I claim as my invention, and desire to secure by Letters Patent:

1. Thecombination of a door post having a vertical groove, a side sillhaving a front recess near its top, a plate secured to the side,

sill adjacent to the recess thereof, a late metal door hinged to thedoor post, a bar secured to-the inner side of the door and adapted toenter said vertical groove, an angle plate secured to the bottom of thedoor and fitting over the plate of the side sill, and a facing platesecured to the top of the side sill in substantially the same horizontalplane as the angle plate of the door.

3. The combination ofdoor posts each hav ing a vertical groove, a sidesill, a roof side plate, two metal door leaves hinged to the door postsand substantially abutting on their opposite sides, a 2 bar secured tothe inner side of each door and adapted to-enter a vertical groove,clips secured to the roof side plate and side sill, latches sliding in.e'eeeeo said clips, and lap plates secured to the inner and outer sidesof the door leaves and covering the joint thereof.

4. A plate metal car door having angle plates secured to its inner sideat the top and bottom thereof, angle iron diagonal braces intermediatesaid angle plates, hinge plates secured to its outer side and e b211-secured to its inner side and projecting out- 10 Wardly therefromopposite the hinge plates.

5. The eombinaiion of a door post having e vertical groove a -metal doorhinged to said door post and a Z leer secured to the inner side of thedoor'and adapted to enier the groove of the door post.
